iStorage datAshur SD is a secure, encrypted microSD card that lets you create multiple drives with the same encryption key, making it ideal for sharing data securely or creating backups. With a Common Criteria EAL5+ certified secure microprocessor, your data is protected by military-grade encryption, ensuring that only authorized users can access it. You can clone as many drives as you need using any standard USB hub, and the process is protected by a secure protocol that never reveals the encryption key or decrypted data.

datAshur SD KeyWriter Application
The patented iStorage datAshur SD KeyWriter application allows users to clone as many drives as required with the same
encrypted encryption key, thereby enabling secondary drives to be cloned as backups and also allows organisations to share
encrypted iStorage microSD cards with as many authorised users of cloned datAshur SD drives as required, without
compromising on data security.
Key features
datAshur SD KeyWriter application clones all critical security parameters including the randomly generated encryption key, all
PINs and administrator defined configurations between the Master datAshur SD drive and as many secondary datAshur SD
drives as required using any off the shelf USB hub (we recommend using a 10 port USB hub), allowing authorised users to
securely share data stored on iStorage microSD cards with one another.
The critical security parameters never leave the datAshur SD drive and are stored in a Common Criteria EAL 5+ certified
secure microprocessor.
The process of cloning the encrypted encryption key and all critical credentials between the Master datAshur SD drive and
secondary datAshur SD drives is protected by a secure protocol incorporated within the iStorage datAshur SD secure
microcontroller. The protocol is implemented using cryptographic algorithms, all of which are FIPS certified. Every datAshur
SD drive has a unique certificate issued by a root of trust, which ensures that only iStorage datAshur SD drives can be used
during the key exchange process.
The datAshur SD drive will never output the established session key when running the secure protocol and the sensitive data
being copied is only decrypted in the validated recipient datAshur SD drive.
The iStorage KeyWriter software (app) running on the PC coordinates the operations required by the secure protocol, however
the software has zero visibility of both the session key and decrypted data, making it impossible for a hacker to access or
retrieve any critical security parameters stored within the datAshur SD drive.

Important!
Before Cloning: As you will be cloning all security parameters from one datAshur SD drive (Master Device) to any number
of secondary datAshur SD drives, it is important to ensure the ‘Master Device’ has been pre-configured by the administrator
to include as many of the following configurable features.
Please refer to the datAshur SD user manual for detailed instructions on how to configure the datAshur SD drive.
Setting the Master Device
Note: The Admin PIN is automatically cloned from the Master device to all connected secondary drives.
Note: If your datAshur SD drive has been disabled from cloning, refer to section 39 of the datAshur SD user manual for
detailed instructions of how to enable KeyWriter cloning and configuration of all the other security features.
Remember: You will be required to enter your KeyWriter PIN each time you launch the datAshur SD KeyWriter
app. This is the PIN that was sent in an email to you together with the license number. The KeyWriter app PIN can be
changed see section 4: ‘Change your KeyWriter PIN’. In addition, ensure your ‘Master Device’ is unlocked and
connected to your computer before setting the Master device.
